Background and Data

COVID-19 is causing havoc in Oregon once again, and as numbers continue to spike, I decided to revisit one the of the first projects I worked on in R Studio. That project can be seen here, and used data from Johns Hopkins. However, because that data is no longer updated this investigation will use data from the NY times that has more current data. The repository for the NY Times data can be found here, and the datasets that are being included are :

  1. us.states : state level data (file description here)

  2. us.counties : county-level data (file description here)

  3. colleges : number of reported cases among students and employees at American colleges and universities, updated May 26th (file description here)

  4. mask_use : survey between July 2 and July 14 (2020) where participants were asked, “How oftern do you wear a mask in public when you expect to be within six feet of another person?” (file description here)

  5. vacc: state level COVID-19 daily vaccination numbers time series data from the Johns Hopkins University repository (file description here)

  6. policytrackerOR: dates and description of policies going into/out of effect in Oregon. To load data for a particular state go to here, find the name of the state file you want to work with.

Here is the data :

us.states <- read_csv('https://raw.githubusercontent.com/nytimes/covid-19-data/master/us-states.csv')
us.counties <- read_csv('https://raw.githubusercontent.com/nytimes/covid-19-data/master/us-counties.csv')
colleges <- read_csv('https://raw.githubusercontent.com/nytimes/covid-19-data/master/colleges/colleges.csv')
mask_use <- read_csv('https://raw.githubusercontent.com/nytimes/covid-19-data/master/colleges/colleges.csv')
vacc <- read_csv("https://raw.githubusercontent.com/govex/COVID-19/master/data_tables/vaccine_data/us_data/time_series/people_vaccinated_us_timeline.csv")
policytrackerOR <- read_csv("https://raw.githubusercontent.com/govex/COVID-19/govex_data/data_tables/policy_data/table_data/Current/Oregon_policy.csv")

The projected cited above mainly looked at the case, death, and vaccination numbers per state to compare highly and mildly impacted states. In this project I will look at highly impacted states and the counties of Oregon. Additionally this project will use population and density data from the tidycensus package. I discuss more about how I got this data using an API in a blog post here. Note that this data is from 2019, which is a couple years older than the COVID data.

# tidycensus
# State : POP and DENSITY data 
state.pop <- get_estimates(geography = "state", year = 2019, variable =  "POP") %>% rename ("state" = NAME, "population" = value)
state.den <- get_estimates(geography = "state", year = 2019, variable =  "DENSITY") %>% rename ("state" = NAME, "density" = value)
# OREGON : POP and Density data 
or.county.pop <- get_estimates(geography = "county", state = "OR", year = 2019, variable = "POP") %>% rename ("county" = NAME, "population" = value)
or.county.den <- get_estimates(geography = "county", state = "OR", year = 2019, variable = "DENSITY") %>% rename ("county" = NAME, "density" = value)

Wrangling the Data

The COVID data set is already in long form (meaning the dates are in rows instead of columns), and the date is already saved as a date variable. Therefore the main tasks here are to join the us.states data set with the vaccination records, and population estimates. Then join the us.states.vacc with the population data and create new percentage columns.

## # A tibble: 5 × 12
##   date       state      population density cases     case.per deaths perc.deaths
##   <date>     <chr>           <dbl>   <dbl> <dbl>        <dbl>  <dbl>       <dbl>
## 1 2020-01-21 Washington    7614893    115.     1 0.000000131       0           0

## # … with 4 more variables: full.vacc <dbl>, full.vacc.perc <dbl>,
## #   part.vacc <dbl>, part.vacc.perc <dbl>

Note: People_Fully_Vaccinated and People_Partially_Vaccinated show as NA because of the dates displayed were before the vaccine was released.

Next, to join the Oregon county population data with the density data, remove “County, Oregon” from each county object, filter out Oregon from the us.counties data, and then join with the population data per county.
